It's of value independent of that.  Tuples of ints used as keys and set elements are very important, and I doubt we'll ever give up on that `hash(i) == i` for the typically "not huge" ints used in such contexts.  Jeroen gave a reasonable example of how boosting the multiplier can help in a case of that above:
